This is the earliest variant of the CD 102 Pony. From 1878 to 1882, Brookfield marked these with only patent dates, prior to moving to the 45 Cliff St. address. A nice yellow-green color is rare in these, and even better still, this guy is close to perfect condition! This is the "11" shop mark, ... the same one most of the purples are found in. Nice and sparkly and rare earliest of ponies! $225 and I'll pay postage in the US.
